TECHNICAL FIELD

The present invention relates to a discharging equipment for medicalprocedure for discharging gas and liquid pooling in a chest cavity andabdominal cavity, and collecting the liquid.

A chest is continuously distensible by a negative pressure (−5˜−20cmH₂O) kept always in a normal chest cavity. If this condition isdisturbed by a pneumothorax, external breast injury or the like, thechest cannot be distended sufficiently so that an affection ofventilation occurs. While in a medical equipment for medical treatmenton a body cavity, particularly a breast of pneumothorax or the like, acatheter is positioned in a chest cavity and connected to a reservoirtank to discharge a liquid and gas, a method of using a containerincluding a tubule connected to the catheter and sealed with water andan air inlet port at a vicinity of an upper part thereof, and a methodof connecting a check valve kit as a so-called flatter valve to thecatheter and connecting a bag or a bottle-shaped container to the checkvalve kit to collect the liquid are used.

Since in the former method, numerous operations and cares are necessaryfor the water sealing in the container on supplying the water,preventing the water from being leaked, and preventing the water frommoving upward in the tubule sealed with the water when a water height isincreased by the discharge of the liquid, and a great size of thecontainer is used for safety, it is inconvenient for portability. Sincein the latter method, a complicated operation of connecting the checkvalve kit as the flatter valve to the container as the bag or the likeis needed and the check valve kit and the bag or the like are arrangedin series when being carried, its size is great and it is not suitablefor the portability.

In order to improve this, the applicant discloses for particularlyimproving the portability in JP-A-61-90669 an all-in-one kit in whichthe check valve is incorporated in the reservoir tank, and wherebybasically, the operation is completed by connecting only the all-in-onekit as the invented matter after the catheter is positioned.

However, since a storage of the discharged liquid amount is consideredfor this all-in-one kit, the check valve is arranged above a containerbody, so that is has an excessively large size for a patient ofpneumothorax with a small amount of the discharged liquid, and itsdownsizing is required. On another aspect, when using the prior artequipments including this all-in-one kit, a further equipment forperforming compulsory discharge of the air from a syringe, aspirationpump or the like needs to be used for quickly discharging the air fromthe chest cavity just after being connected to the patient and releasinga clog from the catheter, so that an excessive cost is necessary.Further, when the catheter of the prior art equipment is positioned inthe abdominal cavity, a partial anesthesia is performed on a portion ofa chest wall to be penetrated, a tissue is incised along a small length,the catheter is inserted, and a penetrating needle incorporated in thecatheter is drawn out therefrom when a forward end of the catheterreaches inside of the chest cavity. On this situation, since anatmospheric air proceeds into the chest cavity through the catheter, itis difficult for the negative pressure to be kept at the inside of thechest cavity, and a positioning operation necessarily should be done inan operating room with the clean atmospheric air. Further, as a problemon the insertion and penetration, there is a probability of that thechest wall of small thickness of a small child is penetrated on theinsertion and penetration, and there is a probability of that the chestof a corpulent patient with a large thickness of the chest wall ispenetrated because of a difficulty in finding an arrival into the chestcavity.

DISCLOSURE OF THE INVENTION

A purpose of the invention is to solve these prior art problems,particularly to provide a discharging equipment for medical procedure ona case where an amount of discharged liquid is small, in which a sizethereof is smaller, a manual operation for discharging can be performedin itself without using any other necessary equipment, the atmosphericair is prevented from proceeding into the chest cavity when thepenetrating needle is drawn out, and the catheter can be safely insertedinto and detained in the chest cavity with using additionally a cannulaneedle, a guide wire and a dilator when the catheter is inserted into achild and a fleshy patient.

The invention is explained below in detail on the drawings. FIGS. 1-10are views showing structures of discharging equipments for medicalprocedure as embodiments of the invention, FIG. 1 including a front view(a) and a side view (b) showing a situation in which a storage bottleand a connector cap are connected, wherein (a) is a front view and (b)is a side view, FIG. 2 is a view showing a situation in which theconnector cap is removed from the storage bottle, FIG. 3 is a viewshowing a situation in which a coupling device and a detachablyconnecting device are connected and a situation in which the couplingdevice and the detachably connecting device are disconnected, FIG. 4 isan oblique projection view of the storage bottle, FIG. 5 is a viewshowing a situation in which a penetrating needle is inserted through apenetrating needle insert port of the catheter, FIG. 6 is a view showinga situation in which the penetrating needle is drawn out through thepenetrating needle insert port of the catheter, FIG. 7 is a view showinga situation in which the storage bottle is connected to the catheter,FIG. 8 is a view showing another embodiment of the invention, FIG. 9 isa view showing a situation in which an adapter with a connector isconnected to the catheter, and FIG. 10 is a view showing other elementsof the invention usable in Seldinger method.

As shown in FIGS. 1 and 2, the storage bottle (1) has an inlet port(26), an outlet port (3) and a discharge port (4), and may have a scalefor measuring an amount of discharged liquid on a side surface thereofif necessary. The inlet port (26) receives gas and liquid pooling in achest cavity to be collected through a catheter into the storage bottle(1). The outlet port (3) discharges the stored liquid, and haspreferably an opening area sufficient for exchanging the liquid to bedischarged and an external air only through the outlet port (3) becausethe storage bottle (1) has no air relief root to form a closed system. Adetachably connecting device (5) for a connector cap (2) is formedintegrally on the outlet port (3), and may be a mechanism in which acoupling device (12) of the connector cap (2) is pressed upward torelease a fitting (for example, a snap fitting) with the connectingdevice (5) by pressing left and right release levers (6) toward eachother to be deformed as shown in FIG. 3, while the structure of thedetachably connecting device (5) is not limited to this embodiment. Amaterial of the detachably connecting device (5) may be hard vinylchloride, ABS resin or the like for bearing a plurality of stressapplying times.

The storage bottle (1) is preferably compact for improving a portabilityand a flat container of aspect ratio 20-60% suitable for fitting onto abody surface, and is produced through a blow molding advantageous forproducing cost. A product through the blow molding for the storagebottle (1) will be explained in detail hereafter, it is important that athickness of a flat cross section is made as constant as possible overthe whole thereof so that the storage bottle (1) bears a pumpingoperation (recover in shape in response to a separation from a handafter being compressed) and a flash is prevented to the utmost frombeing formed on a mating face of the blow mold during the molding sothat a durability thereof on the pumping operation is kept. Generally, aparison having a relatively small diameter with respect to a traversewidth of the product of molding is used to prevent the flash from beingformed, but for the flat product of molding, a small diameter directionof the flat cross section thereof is set firstly in the mold to restrainan expansion of the resin so that the product of molding has a smallthickness in a large diameter direction. Therefore, the parison has adifference in thickness and a large thickness side of the parison havingthe difference in thickness is arranged in a longitudinal direction ofthe flat shape of the storage bottle so that the thickness is madeconstant.

Further, the material of the storage bottle (1) is preferably a plasticor rubber to obtain a transparency for visibility of a movement of thecheck valve and a condition of the discharged liquid and an elasticityfor the pumping. The check valve B (11) has a flat tube shape of softmaterial such as the plastic and the rubber, and a front end at whichinner surfaces thereof contact each other tightly in such a manner thata gas flow discharged from the body can open the contact area to bedischarged but prevent a reverse direction flow.

The connector cap (2) is detachably connectable to the outlet port (3)of the storage bottle (1), and has the coupling device (12) at a fittingportion thereof to form a pair with, for example, the outlet port (3) asdescribed above so that a hermetic sealing is kept when being connected,while a preferable embodiment thereof has a packing therein to keepsecurely the hermetic sealing. The check valve A (8) openable toward thestorage bottle (1) is mounted on the connector cap (2), and a connectorA (7) connectable to the catheter (18) retained in the patient ismounted on an upper portion of the connector cap (2).

Further, in order to prevent contaminant bacteria from adhering to thecheck valve A (8) when the connector cap (2) is removed from the storagebottle (1), a protect cover (9) openable at a forward end side ismounted on an outside of the check valve A (8). Therefore, the checkvalve A (8) needs to be embedded entirely in the protect cover (9), anda front end position (A dimension in FIG. 1) is preferably lowered bynot less than 5 mm. The check valve A (8) has the same structure as theabove described check valve B (11), wherein the protect cover (9) ispreferably made of hard material such as plastic, glass or the like toobtain the transparency for the visibility of the motion of the checkvalve A (8) and the protect of the check valve A (8).

An arrangement of the check valve A (8) of the connector cap (2) and theprotect cover (9) with respect to the storage bottle (1) is describedhere in detail. In a basic case for consideration, the amount of thedischarged liquid is small, and for further downsizing, the protectcover (9) including the check valve (8) is arranged in the storagebottle (1). While the protect cover (9) prevents the contaminantbacteria from adhering after the removal as described above, the frontend of the check valve A (8) needs to be prevented by the protect cover(9) from being clogged by a contact between the check valve (8) and thedischarged liquid pooling in the storage bottle (1), whereby the frontend opening portion of the protect cover (9) needs to be arranged at aposition where the contact with the discharged liquid is made asdifficult as possible.

Therefore, for preventing the discharged liquid from flowing into theprotect cover (9) when the discharged liquid is ascended upward on theside wall of the storage bottle (1) by the movement of the patientduring carrying, it is preferable for a clearance to be formed betweenthe inner wall of the storage bottle (1) and the protect cover (9).Further, since the storage bottle is carried by the patient as a generaluse condition, a bottom surface on FIG. 1 becomes an lower surface whenthe patient stands up, and a back surface becomes the lower surface whenthe patient lies. On the basis of this, the arrangement is determinedfrom the outer dimension of the storage bottle (1) and an anticipatedamount of the discharged liquid in such a manner that the contact isprevented at each of the case where the bottom surface on FIG. 1 is thelower surface and the case where the back surface is the lower surfacewhen the anticipated amount of the discharged liquid is stored.Particularly, the distance (B dimension in FIG. 1) between the storagebottle (1) and the protect cover (9) is preferably made not more than 5mm.

Further, it is preferable for improving the portability of the inventedmatter that various carrier means are incorporated, for example, acarrier clip mounted integrally or detachably on the upper portion ofthe storage bottle (1) or the connector cap (2), or an adhesive tape orthe like attached to the back surface of the storage bottle (1) areusable in consideration of cost and operationality.

Further, an embodiment in which a connector B (10) for being coupled toa connection tube of the suction source for temporary low pressurecontinuous suction is mounted on a front end of the check valve B (11)of the discharge port (4) as shown in FIG. 8, or in which the connectorcap (2) is detachably connectable to the adapter (14) with the connectorB (10) through the same connecting means as the storage bottle (1) ispreferable.

Next, a discharging equipment for medical procedure in which thecatheter (18), the connector cap (2) and the check valve A (8) areintegral with each other is explained. FIG. 5 shows that the penetratingneedle (15) is inserted from the penetrating needle insert port (21) ofthe catheter (18), and FIG. 6 shows that the penetrating needle (15) isdrawn out of the penetrating needle insert port (21) of the catheter(18). The penetrating needle (15) includes a double needle of an innerneedle (16) and an outer tube needle (17) as metallic products ofstainless steel or the like, while materials thereof should not belimited specifically. A step between the inner needle (16) and the outertube needle (17) is preferably 0.15-0.50 mm to abut on a front tip (19)of the catheter (18) and prevent the penetrating needle (15) fromprojecting from the catheter (18). This is caused by that when beingless than 0.15-0.50 mm, there is a risk of that the penetrating needle(15) proceeds over the front tip (19) to penetrate the chest at a frontof the needle when the penetrating needle (15) and the catheter (18) areinserted into the chest cavity. Further, when being more than 0.5 mm, adiameter of the catheter becomes large to cause a probability of a highdamage for the patient. Practically, a dimension of the step ispreferably 0.3 mm.

The catheter (18) has the penetrating needle insert port (21), and theintegrally formed or X-ray impermeable front tip (19) is mounted on thefront end of the catheter (18) so that the penetrating needle (15) isprevented by the step between the inner needle (16) and the outer tubeneedle (17) from projecting from the catheter (18). In the vicinity ofthe front end of the catheter (18), at least one side holes (20) opensto discharge efficiently the gas and liquid in the chest cavity, and onthe back end of the catheter (18), the connector cap (2) including thecheck valve A (8) openable to the connecting side for the storage bottle(1) is mounted.

The penetrating needle insert port (21) is an insert port for insertingthe penetrating needle (15) into the catheter (18), and the penetratingneedle insert port (21) of a notch shape with a size for receiving thepenetrating needle preferably has a dimension and shape for preventing aresistance of the penetrating needle insert port (21) against awithdrawal of the outer tube needle (17) when the catheter (18) is drawnout after the medical procedure while a length of the notch shape ispreferably 1-10 mm. It is practically preferable that a length of thecatheter (18) is 250-400 mm, and an outer diameter of the catheter (18)is 1-3 mm. A position of the penetrating needle insert port (21) ispreferably 30-150 mm when taking a retaining length of the catheter (18)in the chest cavity into consideration. When being less than 30 mm, itis difficult for an adhering portion of the front tip (19) on thecatheter (18) and a position of the side hole (20) to be maintained, andwhen being more than 150 mm, there is a risk of that the atmospheric airproceeds into the chest cavity through the catheter (18).

Next, a method for using the discharge equipment for medical procedureof the invention is explained concretely. A skin on the penetratingportion is sanitized and after local anesthesia, cut shortly inaccordance with a thickness of the catheter, and after retaining thecatheter in the patient, the connector A (7) is connected to theterminating end of the catheter to complete the setting. Alternatively,after inserting the catheter (18) integrally including the connector cap(2) and the check valve A (8) to penetrate, the penetrating needle (15)is drawn out of the catheter (18), the front end of the catheter (18) isretained at an appropriate position in the chest cavity, and theconnector cap (2) is connected to the outlet port (3) of the storagebottle (1) to finish the setting. In general, the above methods areusable, but for corpulent or child patients, the insertion with theSeldinger method (a catheter inserting method with using a guide wire)is preferable. At first, the cannula needle is inserted to penetrate.The guide wire (24) is inserted along a cannula envelope (23), and thecannula envelope (23) is drawn out. A dilator (25) is inserted along theguide wire (24) to enlarge the penetrating route. In a condition inwhich the dilator (25) is drawn out and the catheter (18) holds thereinthe outer tube needle (17) while the inner needle (16) is drawn out, thecatheter (18) is inserted into the chest cavity along the guide wire(24). The retaining is finished by drawing out the outer tube needle(17) and the guide wire (24), and the connector cap (2) at the back endof the catheter (18) is connected to the outlet port (3) of the storagebottle (1).

When the liquid and gas in the chest cavity need to be dischargedrapidly on setting, a compulsory discharge from the chest cavity can beperformed by pumping the storage bottle to open and close alternatelythe check valve A (7) and the check valve B (11). When the dischargedliquid such as pleural effusion or the like pools in the storage bottle(1), release levers (9) of the detachably connecting device (5) arepressed inward toward each other to be deformed to remove the connectorcap (2) so that the discharged liquid is discharged from the outlet port(3). In this time, the atmospheric air is prevented from proceeding intothe chest cavity through the check valve A (8) attached to the connectorcap (2).

Industrial Applicability

The discharge equipment for medical procedure of the invention is morecompact particularly for cases of small discharged liquid, in which anmanual discharge operation can be performed without additional necessaryequipment, and the atmospheric air is prevented by the check valvearranged on the back end of the catheter to open only toward theexterior from proceeding into the chest cavity when the penetratingneedle is drawn out, so that it is usable as a low cost simpleequipment.
